DUMPING-BOX.

To all whom it may concern:

Be it known that I, J OSEPII P. DELANEY, a citizen of the United States,residing at Green Bay, county of Brown, and State of Wisconsin, haveinvented new and useful Improvements in Dumping-Boxes, of which thefollowing is a specification.

My invention relates to improvements in dumping boxes with especialreference to that class of boxes used by graders upon wagons or otherportable vehicles.

-The object of my invention is to provide means whereby the contents ofthe box may be discharged between the walls and at the sides of thereach bar through suitable door ways provided for that purpose, thedoor, when released from closed position, being arranged to swingdownwardly and inwardly under the weight of the contents, and the wallsof the box being arranged to direct the material toward the openingsthus formed, whereby the entire contents of the box will discharge bygravity as soon as such doors are open.

In the following descri tion reference is had to the accompanying crawings, in which,

Figure 1 is a side View of a box embodying my invention showing thedoors in closed position. Fig- 2 is a plan view of the same. Fig. 3 is aview of the box as seen from the underside, and Fig. 1 is a rear endelevation.

Like parts are identified by the same reference characters throughoutthe several views.

The box is preferabl formed with vertical side walls 1 having a aringupper portion 2, and inner end walls 3 and 4 extending down wardly andinwardly from the upper margin of the box to points in the bottom wallwithin the lines of the bolster receiving cleats 5. The bottom of thebox, at least between the end walls 3 and 4, inclines laterally anddownwardly from the longitudinal center line 6, and the outer portion ofeach sloping bottom wall is provided with an opening adapted to beclosed by means of a door 7 these doors being hinged to the bottom alongtheir inner margins, preferably by means of the rod 10 and rod receivingleaves or butts 11.

Each of thedoors are reinforced on the underside by metallic frame bars12, and the outer margin of the door is provided with a supportingmember 13 comprising a bar offset in its central portion to projectbeyond Specification of Letters Patent.

the bottom of the box, and arranged with its ends riveted to one of theframe bars 12. This member 13 is connected with one arm of the doorsupporting lever 14 by means of a rod 15 and link 16, the link beingemployed to connect the upper end of the rod with the lever and thelower end of the rod 15being connected with the member 13 by a yoke 17.

The other arm of the lever is adapted to be engaged by a fastening clip18 when the door is in a closed position, the fastening clip beingadapted to normally hold the lever in such position until it is manuallyreleased by moving this end of the lever outwardly from under thelaterally projecting shoulder 19 of the clip. The lever is connectedwith the vertical side wall 1 of the box by means of a fulcrum pin 20,and the load arm of the lever is preferably arranged to project upwardlyand rearwardly from the fulcrum pin to the point of connection of thelink 16. When-the lever is released from the fastening clip, the door ispermitted to drop by gravity, the upper end of the rod 15 swingingoutwardly and the lower end inwardly as the door swings on its hinges.The link 16 will of course limit the swinging movement of the rod 15 andwill thus also limit the movement of the door, which, when in openposition, is still preferably inclined laterally to some extent andadapted to guide the discharged material toward the side of the wagon.WVhen it is desired to again close the door, the rod 15 serves as alever during the initial movement of the lever 14, thus drawing firstoutwardly and then upwardly on the door. The space underneath the rearinner wall 4 and between such floor and the bottom of the box ispreferably utilized as a receptacle for tools by providing the outerrear wall 22 with a door fixed and swinging sections, hinges connectingthe inner margins of the swinging sections with the fixed sections,operating levers pivotally secured to the respective sides of the box,rods, unconnected at any fixed point and having their lower ends looselyconnected with the outer margins of the swinging sections, and linksconnecting the upper ends of such rods with the operating 1evers,saidrods being arranged for fulcrurn bearing contact with the lower marginsof the side walls during the initial closing movement of the swingingsections.

In testimony whereof I afiiX my signature in the presence of twowitnesses.
